Abstract: An anti-corrosion fogging device for internal combustion engines, such as marine engines, includes a system which injects oil having anti-corrosive properties into the engine of a boat. The device may be applied to two cycle outboard motors as well as four cycle engines. The system dispenses the anti-corrosive oil by means of an aerosol spray can permanently connected to a remotely controlled solenoid valve which through a hose supplies oil to a spray nozzle permanently installed on the engine. A user can at will dispense a controllable quantity of anti-corrosive oil into an internal combustion engine at the end of an operating cycle to protect the engine against corrosion during prolonged idleness.
